Specific skirmish/multiplayer notes:

Some of the file below doesn’t apply to skirmish scripts! Make your changes to player0.slo and vlo -> player7.slo and vlo.

Introduction

In order for Warzone scripts to function properly two files are required: a file with a .slo extension and a file with a .vlo extension.

A .slo file is the main part of the script and holds executable instructions while the .vlo file holds additional variable declarations necessary for the .slo file to function properly.

It is common for a script to deal with new or existing game components such as research topics, structures, unit bodies, propulsions, weapons etc. All these components are defined in appropriate text files like body.txt, structure.txt etc. If you want to use any of these components in your script - in your .slo file - like for example if you want to place certain structures on the map using scripts or enable certain research, you must first make these components available to your script by defining them in a .vlo file.

Roughly said a .slo file is equivalent to a “.c” file and .vlo to a header file in C/C++.

Comments

There are two type of comment for the script language. A multi-line comment is started by the characters /* and finishes with */. A single line comment is started by //.

Vlo Files Explained

When writing a script it is usually known what data (as defined in data .txt files, located in ‘stats’ folder) will be used in the script, so it's a good idea to start writing the script with a .vlo file.

Vlo files are structured as follows:

script "myScript.slo"

run

{

<variable_definitions>

}

In the first line a .slo file is attached to this particular .vlo file. variable_definitions that resides inside the curly braces is the heart of every .vlo file, it contains definitions of the data that will be used in the main script part - the .slo file. Each variable definition starts on a new line and is structured as follows:

<variable_name> <variable_type> <variable_value>

NOTE: Available data types are covered later.

For example if you want to have access to certain droid bodies, like "Python" in your script you have to define it in your .vlo file and assign it to a variable of type BODY with some descriptive name, like:

myPythonBody BODY "Body11ABT"

"Body11ABT" is an internal name of the "Python" body used by warzone, it is defined in the body.txt file. Since it is a string it must be put inside quotation marks. All components, be it some research, structure, droid template or a weapon is refered by its internal name in the game and are defined in the appropriate txt data files.

Each variable definition in a .vlo file starts on the new line and ends at the end of the line.

It is also possible to define arrays of some data type. For example if you want to use the following 3 research topics in your script you might want to define them like this:

myResearch[0] RESEARCHSTAT "R-Vehicle-Body11"

myResearch[1] RESEARCHSTAT "R-Vehicle-Prop-Tracks"

myResearch[2] RESEARCHSTAT "R-Vehicle-Prop-Hover"

This defines an array of size 3 of type RESEARCHSTAT.

Slo Files Explained

As already mentioned .slo file is the heart of every script, it is the place for the executable code. Slo files can be devided into 3 main parts:

1. Variable declarations

2. Event and function declaration

3. Executable code

Variables used throughout the script are defined in the Variable declarations part, with exception of the local variables, which are explained later.

For the .slo file to be able to access variables declared in the .vlo file they must be declared as public variables in the corresponding .slo file.

Coming back to the two examples above you will have to add following lines to the .slo file:

public BODY myPythonBody;

public RESEARCHSTAT myResearch[3];

Keyword public signals that the variable is defined in the corresponding .vlo files. Note that unlike in .vlo files variable declarations in .slo files end with a semicolon and unlike in .vlo files it is possible to declare more than one variable of the same type at once.

More generally a variable declaration in a .slo file looks like this:

<storage> <variable_type> <variable_name1> [, <variable_name2> , ...];

storage is one of “public” or “private”. Public means that the variable is declared and defined in the corresponding .vlo file. Private means the value is only used in the .slo file. Unlike local variables public and private variables are global variables that can be access from anywhere in the .slo file.

NOTE: All variables are initialized to their default values when created. STRUCTURE/DROID/FEATURE variables are initialized to NULLOBJECT, STRINGs to "", FLOATs to 0.0, INTs to 0, BOOLs to FALSE etc.

Event/Trigger Concept Explained

In Warzone scripts executable code consists of events. An event is a list of instructions activated by some trigger attached to it. Event defines what to do, a trigger defines when to run an event, ie when to execute the code inside an event.

All events are structured as follows:

event <event_name>(<trigger>)

{

<code>

}

Example:

event myFirstEvent(every, 50)

{

console("Hello world!");

}

This piece of code will output "Hello world!" to the game console every 5 seconds. Note that triggers are put inside the round braces after the event name while code that is to be executed resides inside the curly braces. The syntax of the executable code is very close to the C/C++ syntax.

The only difference between a WZ event and a function as used in programming languages like C/C++ is that an event is not called or activated by another function, but rather by a trigger attached to it.

It is always possible to interrupt execution of an event with the exit keyword, which is a counterpart of the return keyword used for functions; exit keyword does not deactivate an event.

Example:

event myEvent(every, 10) //run every second

{

console ( “this text will be printed every second” );

if( (gameTime / 10) > 60) //did more than a minute pass?

{

exit; //anything that comes after ‘exit’ will not be executed

console( “this text will only get printed in the first” );

}

}

Events must be defined before they can be referenced. If event definition comes after the place where this event is referenced it is necessary to declare this event beforehand in the Event and function declaration section.

Events are declared like this:

event <event_name>;

Such a declaration reserves identifier used as event name.

Example:

event myEvent; //declaration of the event

...

// another event that references myEvent

event anotherEvent(wait, 10)

{

setEventTrigger(myEvent, inactive); //deactivate myEvent

}

...

// myEvent is defined after being referenced by anotherEvent,

// but it works, since we declared myEvent beforehand

event myEvent(wait, 20)

{

console(“It all compiles, because I was declared beforehand!”);

}

If myEvent wasn’t declared before being referenced by anotherEvent then this example would not compile.

Triggers Explained

In WZ triggers are usually simple timers that repeartedly trigger execution of events, but triggers can also be callbacks (special events that occur in the game, like destruction of a building) that are listed and explained later.

Here are avaiable trigger types:

wait, <time> Run the event after delay <time>.

every, <time> Run the event at every <time> interval.

<callback> Run when callback occurs.

<bool exp>, <time> Run the event if <bool exp> is true, checking every <time> interval.

init Run the event when the script starts.

inactive Do not run the event until a trigger is assigned to it.

NOTE: all time intervals are in 1/10 of a second.

For example every, 10 will trigger every second while wait, 50 will only activate once: 5 seconds after the game has started. If an event has inactive assigned as a trigger this event will never execute unless its trigger is reassigned by some other event with setEventTrigger(<event>, <trigger>) function.

NOTE: complete function and callback listings are given below.

A few examples:

// 1. output text to game console every second

event everySecond(every, 10)

{

console(“The game has started “ + gameTime/10 + “ seconds ago”);

}

// 2. Code inside this event will never execute unless its event is reassigned later

event inactiveEvent(inactive)

{

console(“Someone has just reactivated me!”);

}

// 3. CALL_NEWDROID callback with parameters,

event droidBuilt(CALL_NEWDROID, 5, ref newDroid, ref myFactory)

{

console(“We got a new droid at coordinates ” &

newDroid.x & “-“ & newDroid.y );

}

In the last example droidBuilt event will be triggered everytime a factory belonging to player 5 produces a new droid. newDroid variable refers to the new droid thatb was just built and myFactory to the factory that build this droid. This example assumes that newDroid and myFactory were correctly defined in the Variable Declarations section. For more callbacks see Script Function Callbacks .

NOTE: ref keyword means that a pointer to the provided variable is passed to the interpreter, so that a callback can modify value of the variable.

It is possible to reuse a trigger for more than one event if a trigger is declared in the Event and function declaration. Trigger declaration has following syntax:

trigger <trigger_name> ( <trigger> );

Example:

trigger everySecond ( every, 10 ); //trigger declaration

...

event eventOne( everySecond ) // uses the trigger we declared above

{

...

}

event eventTwo( everySecond ) // uses the trigger we declared above

{

...

}

In this example everySecond trigger is defined outside of an event. Such a trigger can be reused by its name. Note that trigger declaration ends with a semicolon.

String Expressions

Strings are put inside quotation marks: “some text inside quotation marks is a legal string”.

Strings can be easily concatenated using the & operator.

For example: “String1” & “String2” will result in “String1String2”.

Strings can be compared using == operator (case insensitive comparison) or strcmp() function.

Such data types as integers, booleans and floats are automatically converted to strings when it is required, so given the following variable declaration:

private float pi;

private int myInteger;

private string myString;

private bool myBool;

the following line is a valid string expression:

console(“value of pi is “ & pi & “, value of myInteger is “ & myInteger & “,

value of myString is “ & myString & “, value of myBool is “ & myBool);

Numeric Expressions

Numeric expressions are made up of int variables, numeric constants and functions that return int values, e.g.:

power * 32 - basePower

numDroids(player) + 5

The possible operators are :

+ - * /

Increment and decrement operators can only be applied to the integer variables outside of the expression context:

myInteger++;

myInteger--;

There are also a number of operators that compare numeric expressions to give a boolean

expression :

< > Less than / Greater than

<= >= Less or Equal / Greater or Equal

== != Equal / Not Equal

Boolean Expressions

Boolean expressions are made up of bool variables, the boolean constants TRUE and

FALSE and game functions that return a boolean value e.g.:

not droidSeen and attackDroid

The possible operators are:

and or not == !=

The operators == and != can also be used with user defined type variables.

Floating-point Expressions

Floating-point expressions are very similar to integer expressions. There are some differences though: it is not possible to use increment/decrement operators with floating-point variables. The integral and fractional parts of the float constant must be separated by a dot, even if fractional part is 0.

Examples:

myFloat = 1.0 + pi / 2.0 + 3.6;

Floating point expressions can’t be mixed with integer or boolean expressions. To use integers or booleans in floating-point expressions they must be cast to FLOATs first.

For more information about casts refer to Casts.

Assignment

The value of a variable or an expression can be assigned to another using the = character,

e.g.:

currentDroid = foundDroid;

index = base + found * 4;

myString = “some text”;

myFloat = 2.0 + pi / 2.0;

If Statements

If statements are used to control which bits of code are executed. The simplest form is :

if ( <bool exp> )

{

<code>

}

In this form if <bool exp> evaluates to true then the script code <code> is executed,

otherwise the code is ignored.

Examples:

if ( <bool exp> )

{

<code>

}

else

{

<code>

}

if ( <bool exp> )

{

<code>

}

else if ( <bool exp> )

{

<code>

}

else

{

<code>

}

While Statements

While statements allow <code> to be executed while <bool exp> evaluates to TRUE:

while ( <bool exp> )

{

<code>

}

Casts

Casts convert one data type into a different one. In WZ casts are mostly used to convert float to int, int to float and bool to float. To perform a cast write the required data type in paranthesis.

Examples:

myFloat = (float)myInteger + 2.3 + (float)500 + 500.0;

myInteger = 100 + numPlayers + (int)myFloat;

NOTE: Both (float)500 and 500.0 represent the same value. When converting FLOATs to INTs fractional part is discarded.

Custom Functions

It is possible to define custom script functions to reuse certain functionality throughout the script.

Function have following syntax:

function <return type> <function name> ( [ <argument type> < argument name> , ... ] )

{

<code>

return ... ;

}

Examples:

function void displayVictoryMessage( int winner )

{

console ( “Player “ & getPlayerName(winner) & “ has won the game” );

}

function float calculateMinimum ( float f1, float f2 )

{

if ( f1 < f2 )

{

return f1;

}

return f2;

}

Functions look almost identical to their C counterparts, except that the beginning of a function is marked with ‘function’ keyword.

It is possible to declare function, like with events it is done in the Event and function declaration section:

function void displayVictoryMessage( int winner );

function float calculateMinimum ( float f1, float f2 );

Declared this way it is possible to use a function before it is defined later in the script.

To call a function simply provide its name with parameters in paranthesis:

displayVictoryMessage(0);

...

console(“Minimum of 2 and 2.1 is “ & calculateMinimum(2.0, 2.1) );

Like in C

return <return expression>;

or for void functions just:

return;

returns execution to the caller.

Local Variables

Local variables belong either to a function or event where they were declared and are not accessible outside of it. Local variables must be declared at the beginning of the function or event. Like public/private variables local variables of the same type can be declared on the same line separated by a comma.

Declaration of a local variable looks as follows:

local <variable type> <variable name> [, <variablename>, ...] ;

Example:

event myEvent(myTrigger)

{

local int count;

<code>

}

function void myFunction()

{

local DROID myDroid1, myDroid2;

local string myString;

<code>

}

Macros

Warzone Scripting language supports nested macros (current max depth is 10).

Macros are defined as follows:

#define <macro name> <macro body>

Example:

#define pi 3.14

Example of a nested macro:

#define CURRENT_PLAYER 0

#define CURRENT_PLAYER_NAME getPlayerName(CURRENT_PLAYER)

During the compilation process macro names are replaced with the actual code.

Parametrized macros are not supported.

If any other text but “define” follows after # character then anything between # and end of the line is ignored by compiler making it possible to use #region and other tags in your favorite IDE.

NOTE: “#include” is reserved but not fully supported yet.

Data Types

Apart from standard data types like string (string), integer (int), boolean (bool) and floating point (float) there are some warzone-specific data types available:

INTMESSAGE - (simple) Name of a message as defined in Messages.txt, used mostly for campaign. In most cases it is easier to use a string instead.

BASEOBJ - (complex) any of a DROID, FEATURE or STRUCTURE. It is a pointer to some droid/feature/structure on the map, can be NULLOBJECT if it wasn't assigned to a particular droid/feature/structure.
You have access to:

baseobj.x
baseobj.y
baseobj.z
baseobj.id - unique id number
baseobj.player - player id
baseobj.type - one of OBJ_DROID, OBJ_STRUCTURE, OBJ_FEATURE
baseobj.health - %age number of body points left
baseobj.clusterID - the cluster the object is a member of

baseobj.target – target of the object (in case of a multi-turret object returns target of the default weapon)

NOTE: the functions objToDroid, objToStructure and objToFeature exist to convert a BASEOBJ
to a droid, structure or feature if the base obj is of the right type.

DROID - (complex) defined by the ID got from the world editor. It is a pointer to a particular droid on the map, can be NULLOBJECT when no droid is assigned to the DROID variable.
You have access to :

all BASEOBJ variables
droid.order - current order of the droid
droid.orderx - target location of the droid order
droid.ordery - target location of the droid order
droid.action - current action of the droid
droid.body - the BODY of the droid
droid.propulsion - the PROPULSION of the droid
droid.weapon - the WEAPON of the droid DROIDID - (simple) literally just an ID of a droid

droid.selected – holds TRUE if droid is currently selected
droid.group – the GROUP droid belongs to

FEATURE - (complex) defined by the ID got from the world editor. It is a pointer to a map decoration, like a tree, wrecked building, oil resource etc, can be NULLOBJECT.

You have access to :

all BASEOBJ variables

FEATURESTAT - (simple) type of a feature as defined in features.txt.

TEMPLATE - (simple) name of a template as defined in templates.txt

STRUCTURE - (complex) defined by the ID got from the world editor. It is a pointer to a particular structure on the map, can

be NULLOBJECT when no structure is assigned to the STRUCTURE variable.

You have access to :

all BASEOBJ variables
structure.stat - the STRUCTURESTAT of the structure, defined in structures.txt

structure.stattype – structure type (like REF_HQ etc, refer to Script Function Constants)

STRUCTUREID - (simple) literally just an ID of a struct
STRUCTURESTAT - (simple) type of a structure as defined in structures.txt

BODY - (simple) name of a body as defined in body.txt
PROPULSION - (simple) name of a propulsion as defined in propulsion.txt
ECM - (simple) name of a ECM as defined in ecm.txt
SENSOR - (simple) name of a sensor as defined in sensor.txt
CONSTRUCT - (simple) name of a construct as defined in construct.txt
WEAPON - (simple) name of a weapon as defined in weapons.txt
REPAIR - (simple) name of a repair type as defined in Repair.txt
BRAIN - (simple) name of a brain type as defined in Brain.txt
SOUND - (simple) ID of sound used in playSound()
LEVEL - ID of a level as defined in GameDesc.lev
RESEARCHSTAT - (simple) name of a research topic as defined in research.txt

GROUP - (complex) a group of droids. Don't confuse GROUP with in-game units groups that can be accessed with ctrl-<number>, they have nothing in common. GROUP is an internal structure used to simplify unit management.
You have access to :

group.x - average x coord
group.y - average y coord
group.members - number of units in the group
group.health - average %age health of the units

group.type – type of the group, one of: GT_NORMAL, GT_COMMAND or GT_TRANSPORTER (refer to Script Function Constants)

group.commander – commander of the group, if type = GT_COMMAND or NULLOBJECT

NOTE: transporters and commanders can't be added to a GROUP.

With a complex object it is possible to access information specific to the instance of this object. Acomplex object is usually a pointer to a C structure in the code. For example a DROID is a complex object - its x,y,z can be queried whereas a DROIDID (a simple object - an integer) is just a placeholder for the numeric value of the ID.

Script Functions

setSnow(bool)

This function switchs snow on or off. TRUE will turn snow on, FALSE will turn snow off. If rain is on when snow is started the rain will be turned off.

{

do something

}

DROID EnumDroid()

Enumerate through all targetPlayer’s droids that are visible to ‘lookingPlayer’. Returns NULLOBJECT when no more exist.

TEMPLATE getTemplate(COMPONENT, PLAYER)

This function returns the first TEMPLATE based on the stat for the player it can find. It can be any type of component. To use it create a TEMPLATE variable and assign it to the result of the function call. For example:

TEMPLATE myNewTemplate;

WEAPON Rocket;

myNewTemplate = getStructure(Rocket, 0);

This will look through the player 0 list of template to find one which contains a rocket and then return a variable of type TEMPLATE. You will then be able to access its attributes. If a template cannot be found than NULL is returned . It will be worth checking that the TEMPLATE does not equal NULL before using it. For example:

if (myNewTemplate == NULLTEMPLATE)

{

do something

}
